Cotton outshines polyester in comfort, sustainability, and biodegradability. Here’s why:
- Eco-Friendly: Cotton is natural, biodegradable, and uses less non-renewable energy. Polyester, made from petroleum, releases microplastics and requires twice the energy to produce.
- Comfort: Cotton is breathable, soft, and absorbs moisture, making it ideal for sensitive skin. Polyester traps heat and moisture, often feeling less comfortable.
- Environmental Impact: Organic cotton farming reduces water use by 91% and avoids harmful chemicals. Polyester production contributes to microplastic pollution and higher carbon emissions.
- Durability vs. Maintenance: Polyester is more durable and low-maintenance but pollutes during washing. Cotton requires more care but breaks down naturally.

Quick Comparison
| Feature | Cotton | Polyester |
|---|---|---|
| Origin | Natural (cotton plant) | Synthetic (petroleum) |
| Biodegradability | Yes | No |
| Energy Use | Lower | Twice as high |
| Water Usage | Higher (124 m³/kg) | Lower (2.9 m³/kg) |
| Microplastic Pollution | None | Significant |
| Comfort | Soft, breathable, absorbs moisture | Traps heat, less breathable |
| Durability | Moderate | High |
Cotton’s natural benefits make it a better choice for comfort and the planet, while polyester’s durability comes with environmental trade-offs.
Environmental Impact Comparison
Cotton and polyester differ greatly when it comes to their impact on the environment.
Cotton: Natural and Biodegradable
Cotton breaks down naturally, giving it an advantage over synthetic fibers. Organic cotton, in particular, uses 91% less fresh water because it avoids chemical pesticides and fertilizers [5]. Organic farming also helps maintain soil health, conserve rainwater, and eliminates harmful chemical use.
Polyester: Petroleum-Based and Polluting
Polyester's reliance on petroleum makes it less eco-friendly. Producing one polyester shirt generates 12.1 pounds of carbon emissions, compared to 9.5 pounds for cotton [4]. Additionally, polyester and nylon contribute 176,500 metric tons of synthetic microfibers to waterways annually [4]. These microplastics remain in the environment indefinitely, harming marine life.
Environmental Impact Table
| Environmental Factor | Cotton | Polyester |
|---|---|---|
| Global Warming Impact | 9.3 kg CO2-eq/kg | 10.2 kg CO2-eq/kg |
| Energy Consumption | 98 MJ-eq/kg | 184 MJ-eq/kg |
| Water Usage | Higher (124 m3/kg) | Lower (2.9 m3/kg) |
| Biodegradability | Fully biodegradable | Non-biodegradable |
| Microplastic Generation | None | Significant |
"The use of chemical dyes in polyester production contributes to water pollution, as these dyes can contain harmful chemicals that are released into waterways during the dyeing process. This contrasts with cotton, which can be dyed naturally, reducing the environmental impact" [4].
Organic farming methods continue to enhance cotton's eco-friendly reputation. Beyond its environmental advantages, cotton also stands out for its comfort and breathability, making it a practical choice for everyday wear.

Comfort and Breathability Analysis
Cotton and polyester differ quite a bit when it comes to comfort and how they interact with the body.
Cotton: Soft and Breathable
Cotton's natural fibers make it feel gentle on the skin. Its structure includes hollow spaces, known as lumens, which create a natural airflow system. Fun fact: cotton can absorb up to 27 times its weight in water [1].
This natural breathability is a big plus for people with sensitive skin. Many healthcare experts recommend cotton for those with skin conditions because it allows for better air circulation, helping to prevent irritation.
Polyester: Synthetic and Less Comfortable
Polyester's synthetic makeup can limit comfort. Its water-repelling properties mean moisture stays on the skin instead of being absorbed [4]. This often leads to a sticky, warm feeling, especially during workouts or in humid weather.
The lack of natural pores in polyester also means poor ventilation. While cotton feels soft and breathable, polyester's synthetic nature can sometimes make it uncomfortable, particularly for those with sensitive skin.
Comfort and Breathability Table
| Feature | Cotton | Polyester |
|---|---|---|
| Moisture Management | Absorbs up to 27x its weight | Repels water |
| Air Circulation | Allows natural airflow | Limited due to structure |
| Skin Sensitivity | Gentle on sensitive skin | Can cause irritation |
| Temperature Regulation | Naturally cooling | Traps heat |
| Texture | Softens over time | Retains synthetic feel |
"Cotton's natural fibers have hollow openings that allow for better airflow and moisture absorption, making it more comfortable against the skin" [1].
These features make cotton a go-to option for everyday clothing and bedding, offering a strong appeal for comfort-focused consumers. While cotton shines in comfort and breathability, other factors like durability and upkeep bring more to the table for comparison.
Durability and Maintenance Comparison
When choosing fabrics, it's important to weigh both durability and maintenance needs. These factors significantly influence long-term value and environmental effects.
Cotton: Comfort with Some Challenges
Cotton is comfortable but comes with a few durability issues, such as shrinking and wrinkling if not pre-treated. Its wear resistance is moderate, meaning it may show signs of aging faster than synthetic fabrics.
Caring for cotton often requires more water and energy due to its tendency to shrink and wrinkle, making its maintenance less eco-friendly compared to other options.
Polyester: Durable but Problematic
Polyester's synthetic design makes it resistant to wrinkles and stains, ensuring durability and low upkeep. However, it has a major downside: it sheds microfibers during washing, which contributes to water pollution on a large scale.
Durability and Maintenance Table
| Characteristic | Cotton | Polyester |
|---|---|---|
| Wear Resistance | Moderate, shows wear over time | High, maintains shape well |
| Washing Requirements | Hot water, regular cycles | Cold water, quick wash |
| Drying Time | Longer, requires heat | Quick-drying |
| Environmental Impact During Care | Higher water usage | Releases microplastics |
| Energy Consumption | Higher for maintenance | Lower for care, higher for production |
"While cotton has its durability challenges, its biodegradable and renewable nature makes it more sustainable in the long run. Polyester, despite its durability, has significant environmental drawbacks that make it less sustainable" [2][3].
The environmental impact of textiles goes far beyond their production. Maintenance and disposal are equally important in assessing sustainability [6]. For those focused on eco-conscious choices, balancing durability with environmental concerns is essential.
Although polyester offers better durability and requires less maintenance, cotton's biodegradability and comfort give it an edge as a more eco-friendly option overall.
Conclusion: Cotton's Advantages Over Polyester
While polyester stands out for its durability, cotton offers a more environmentally friendly option, making it a responsible choice for the future.
Key Takeaways for Cotton Industry Professionals
